·      What is meant by the tipping point?

-The tipping point = Rapid ethnic turnover.

"In many neighborhoods, an infusion of minorities prompted whites to leave and discouraged other whites from replacing them. Thus the proportion of minority-group members grew quickly, particularly after the minority group became the major force in the community. Real estate agents have historically abetted this process by "steering" purchasers to "live with their own kind." - page 7
